Onion Beef au Jus

Garlic, onions, soy sauce and onion soup mix flavor the tender beef in these savory hot sandwiches served with a tasty, rich broth for dipping. The seasoned beef makes delicious cold sandwiches, too. —Marilyn Brown, West Union, Iowa

    Delicious! Even my picky kid went nuts over this. I did bake the roast the day before and refrigerated it overnight (makes it easier to slice). I only made a 2-lb roast, since it's just 3 of us, and we still had a ton of leftovers for the next day.

    This sounds delicious.. But due to the prices of beef roasts could a person substitute with a pork roast. I know the taste would be altered by using a different meat. But i was wondering if it would any good using a pork roast? Thankyou??

    Hi Vonoepen,I'm not sure ground beef would be appropriate for this recipe.

    This was awesome. I skipped the browning on all sides in oil. I cooked the roast in a crock pot for 8 hours.
